Research plan/methodology: The proposed research is a 3.5-year, two-centre parallel randomized controlled trial for PVD using an intent-to-treat analysis strategy, with pain during intercourse as the primary outcome. The main research questions will be addressed by: 1) recruiting 224 premenopausal women and their partners with medically diagnosed PVD; 2) performing comprehensive gynecological and psychosexual pre-treatment evaluations focusing on our outcome measures; 3) randomly assigning women to one of the two 12-week treatment arms: CBCT or lidocaine, and 4) evaluating pain during intercourse, as well as sexual, psychological and relationship outcomes, in addition to self-reported improvement and treatment satisfaction, post-treatment and at 6-month follow-up. These procedures will take place in two different university centers: Université de Montréal in Montréal, Québec, and Dalhousie University in Halifax, Nova Scotia, and their affiliated hospitals. Both university centres will store data securely, adhering to the protocols outlined by the ethics review boards at each site.
